    due to insufficient horizontal overlap
  32. Immediate dentures:
    are dentures that are inserted immediately after the teeth are extracted
  33. When fabricating immediate dentures:
    since mandibular ridges often lead to an unstable prosthesis, immediate complete mandibular dentures should rarely be fabricated in the mandible
  34. Indication for placement of a dowel and core include
    anterior teeth with RCT and insufficient core structure for final restoration
